This doesn't involve a problem, but I am confused on another part involving velocities and acceleration and such..
My book gives me 4 equations, the first one is:
final Velocity=initial Velocity + (acceleration)(time)
The second one:
distance traveled=(intial Velocity + final Velocity)/2
The third:
distance traveled=(intial Velocity)(time)+1/2(acceleration)(time)squared
And the final:
final Velocity squared=(initial Velocity)squared+2(acceleration)(distance)
My question is, under what circumstances are each equation used? My book gives several problems but it uses all of these without really explaining how to use each one, or under which scenario we use each one..like for example, if I want to find the time it takes to go x distance, traveling at s velocity and accelerating at a, then which one would I use?
